Neutrino Masses and Leptogenesis from Extra Fermions [PDF]
Dmitry V. ZhuridovGeneration of the neutrino masses and leptogenesis in the Standard Model extended by the heavy singlet or/and triplet Majorana fermions is considered. The classification of the leptogenesis scenarios according to the new fermion spectra is given. The particular cases of resonant and freed leptogenesis are discussed.View original: http://arxiv.org/abs/1204.4581
